In a span of a few weeks MLS has managed to snag Dos Santos and Vela from good situations in Spain
I think it's a mistake for both guys, especially Vela, but best of luck to him.
If I was a Mexican supporter I'd be livid. How are 3 of your top players in prime age coming to the USA to play in the MLS? I assume they want to be close to home and LA is a top city in the world to live in.
